A filtration cartridge of a liquid purification device that consists of a filtration zone () and a venting zone (), said filtration zone in turn consists of a housing () filled with a filtration material () and not less than one opening () made in the bottom () of the housing (), said venting zone consists of fixation means () and a lid (), performed so that the filtration material () has a multi-clustered interconnected structure, and the venting zone () is formed so as to retain and preserve the main structure of the filtration material () inside the housing () of the filtration cartridge, by means of the fixation means () being the first retention barrier and made as a grid, the size of mesh () of said grid does preferably not exceed the average size of the filtration material cluster, and the lid () is made as a second retention barrier and formed, with meshes () comprising net sections and a top point () of the lid () is positioned at a distance preferably not more than 1 cm above the fixation means ().

Filter cartridge of water purification system

The invention relates to composite materials, and more particular to composite adsorptive materials for purification of liquids, in particular, a drinking water, on the basis of components of a granulated material and a fibrous material. The new composite material for filtering purifying a liquid on the basis of a mixture of components of granulated and fibrous materials comprises volume zones with adjustable density, which zones create the structure of the material, which structure is self-strengthened when a liquid flows in the course of filtration, wherein, said volume zones make the material most part, each zone is created in the form of a interlaced fiber site, which sites are bonded among themselves by separate fibers, and the space within and between said interlaced fiber sites is filled with a granulated material.

Composite material

Disclosed are filtering cartridge and methods of producing the filtering cartridge for purifying drinking water and other liquids for household, medical and other purposes. A filter cartridge is filled with a filtering material and is configured in the form of an open bowl which can be closed with a lid, having side walls and a bottom with at least one outlet opening which is closed with a water-permeable material, wherein the cartridge bottom is designed such as to make it possible to use the water-permeable material which comes to the external edge of the side walls and is made of fibers with a sufficiently small diameter to allow using the filtering material containing powder particles; furthermore, the entire area between external and internal edges of the walls along the perimeter of the bottom is made of a composite based on a polymer water-permeable material.

Method of producing a filtering cartridge

The invention is directed to purification of liquids, such as drinking water using filters, wherein filtration is effected while the liquid flows upwardly. The invention includes both the method and a device enabling the method to be carried out. The device is constructed to intake impure liquid at the bottom of the filter and initially to effect flow by filling liquid to above the filter outlet near the top, and maintaining flow thereafter by virtue of the presence of a low internal pressure that develops as the liquid passes through the system.
